Predictive models and clinical manifestations of intrapulmonary vascular dilatation and hepatopulmonary syndrome in patients with cirrhosis: Prospective comparative study

Figure 2 Novel biomarkers for intrapulmonary vascular dilatation and hepatopulmonary syndrome in patients with cirrhosis. Comparisons among multiple groups were performed using the Kruskal-Wallis rank sum test. A: Serum sphingosine 1 phosphate concentration; B: Serum angiopoietin-2 concentration; C: Serum platelet-derived growth factor BB concentration. HPS: Hepatopulmonary syndrome; IPVD: Intrapulmonary vascular dilatation; PDGF-BB: Platelet-derived growth factor BB; S1P: Sphingosine 1 phosphate.
